Problems using the elasticsearch php client?

Here is the documentation,

The problem is in the screenshot:

Thank you @lyt8384. I'm a bit confused about the idea. Could you please help me demonstrate the following example:

The effect to be achieved is to enter keywords in the search box in the view and search to get the results. The main problem is that I don’t know how to write the controller.

Note: The package on github seems to have not been updated for a long time. I don’t know how it supports the latest version of elasticsearch, so I want to use the official php client directly.

1. Larvae is automatically loaded, no need to introduce it in the first line, just use the namespace directly. In fact, you can use some packages packaged by others to simplify the use, such as https://github.com/fadion/Bouncy. It's much simpler to use.

2. If you use the one in 1, you won’t have this. . The red box above is a request, which is your operation of filling in the corresponding content into ES. Just write where you need it. For example, add data and modify data. The following is the response. It is ES that tells you that the index is OK.

ES can also be understood as a database. You also need to store data like mysql. Then search. . It's just that his search is very powerful, as well as various calculations and the like. Don't think of ES as a class or component. Once installed, you can search the full text.
